Tac?

[L3GO]

I am thinking about installing TAC to my game and i have 2 space stations in orbit and i was wondering if i need to take my kerbals back to kerbin before i install TAC incase they die? (If you get what i mean)

TAC-LS, presumably?

I'm not sure, but I think they'll be okay. TAC-LS adds a couple of days of life support supplies to each capsule.

You'll want to get a resupply mission up there pronto, though.

In the past I have installed only the TAC parts first without the plugin.

This allowed me to send up the life support parts and dock them to the station without killing anyone.

Then I installed the plugin. I have not done this in a while so back up your save if you try this.

To make it easier for myself i might bring them all home and send up all the food and other items incase something goes wrong.

They won't start to die immediatly. The kerbals will only start to consume resources after they are first come into physices range - 2.5km. Before instalation I checked up on all my kerbals to see if they were in a station where I could add resources to keep them alive. After instalation I built supply ships to go to each station, or rescue ships to bing back the kerbals with enough supplies to get them back ok.
